clk: thead: Add CLK_IGNORE_UNUSED to fix TH1520 boot
[ Upstream commit 037705e94bf6e1810b7f9dc077d0e23292229e74 ]
Add the CLK_IGNORE_UNUSED flag to apb_pclk, cpu2peri_x2h_clk,
perisys_apb2_hclk and perisys_apb3_hclk.
Without this flag, the boot hangs after "clk: Disabling unused clocks"
unless clk_ignore_unused is in the kernel cmdline.
Fixes: ae81b69fd2b1 ("clk: thead: Add support for T-Head TH1520 AP_SUBSYS clocks")
